bpo-32512: Add -m option to profile for profiling modules (#5132)

The new option in the CLI of the profile module allow to profile
executable modules. This change follows the same implementation as the
one already present in `cProfile`.

As the argument is now present on both modules, move the tests to the
common test case to be run with profile as well.
